Iboga, ibogaine, and the terms around them
Iboga generally refers to plant material associated with Tabernanthe iboga, a shrub native to Central Africa. Ibogaine is an alkaloid found in that plant and may also be discussed as an isolated compound. Those words are often used interchangeably in casual conversation, but they point to different things: a plant, plant-derived material, and a specific psychoactive constituent.
That distinction matters because a search result, personal account, or provider description may use broad language that hides important differences in substance, setting, dose, screening, and oversight. The ibogaine reference entry offers a basic taxonomy, while a careful orientation should keep the chemical term separate from wider cultural, commercial, and treatment-related claims.
Working definition
Ibogaine is a psychoactive alkaloid. It is not a general label for every iboga preparation, every setting where iboga is discussed, or every claimed outcome associated with it.
